ELI5: cognitive load

// eli5

What is cognitive load?

Cognitive load is how hard your brain has to work to understand or do something [2]. Think of your brain like a computer with limited space to think about things at once—when you're trying to learn something new or use a confusing website, you're using up that thinking space [3][4].

Why does it matter?

When your brain is overloaded with too much information, it's harder to learn and remember things [3]. If a website or lesson is too complicated, your brain gets tired trying to figure it out instead of actually learning what matters [4].

What makes cognitive load worse?

Too many choices, confusing layouts, or trying to do too many things at once all make your brain work harder [4][5]. It's like trying to juggle while someone keeps throwing more balls at you—eventually you can't handle it all [3].

How do you reduce it?

You can make things simpler by removing extra information, organizing things clearly, and letting people focus on one thing at a time [3][4]. Breaking big tasks into smaller steps also helps because your brain doesn't have to hold as much in its thinking space [2].
